Question 926239
So if you draw a line from one corner to its opposite corner you create a right triangle. That line that you just drew is the hypotenuse. And you know that to find the hypontenuse of a right triangle this is the formula:
a^2 + b^2 = c^2 
So now you substitute:
28^2 + 45^2 = c^2
784 + 2025 = c^2
2809 = c^2 
c = sqrt(2809) 
c = 53 ft
